"[AUTH] invalid user/password (error 999)"

1

My mom and I are receiving the following message repeatedly when we open eM Client or try to send/receive:
Server says “[AUTH] invalid user/password (error 999)”

This is a server sided issue. For more info visit this page: http://answers.yahoo.com/question/ind…

I tried all the solutions suggested by Yahoo, none worked. Looks like an em client issue. Doesn’t happen with thunderbird.

Hello,

this is really Yahoo’s side problem, but in next release there are some Yahoo email authentication workarounds. So it should bug less with their faulty serves.
